By weight · Order from lightest to heaviest.

1. An unfed female mosquito 2.5 mg

   After a full blood meal a mosquito can double or even triple her weight — and still fly away with the loot.

2. A house sparrow 28 g

   House sparrows have followed humans to every continent except Antarctica — one pair even nested deep inside an English coal mine.

3. An adult North American beaver 20 kg

   The largest beaver dam ever found, in Alberta, Canada, stretches about 850 meters and is visible from space.

4. A full-size kitchen refrigerator 135 kg

   Refrigeration changed cuisine more than almost any invention; Einstein even co-patented a fridge with no moving parts in 1930.

5. A fully loaded 18-wheeler semi-truck 36 t

   Fully loaded, a semi needs about 40% more stopping distance than a car — which is why truckers leave that gap you keep filling.

6. An adult male sperm whale 45 t

   Its clicks reach about 230 decibels — the loudest animal sound on Earth — and a third of its body is one giant sonar-focusing nose.
